39cbd83837 Don't return NULL if there's no error message;
return a generic text message instead.
(Someday, I'll track down all the places that
are generating errors but not recording messages. ;-/

Thanks to: Jaakko Heinonen

57b665990a Eliminate reliance on non-portable <err.h> by implementing a very
simple errx() function.
Improve behavior when bzlib/zlib are missing by detecting and
issuing an error message on attempts to read gzip/bzip2 compressed
archives.

c48a83413a Add some functions to query basic facts about the library:
archive_version: Returns a text string, e.g., "libarchive 1.00.000"
   archive_api_version: Returns the SHLIB major version
   archive_api_feature: Returns a feature number useful for answering
     questions such as "Is this recent enough to do XXX?"

The last two also have macros defined in archive.h, so you can compare
the compile-time and run-time environments.  (In particular, you can
compare ARCHIVE_API_VERSION to archive_api_version() to detect library
version mismatches.)

With these in hand, it will soon be time to turn on the
shared-library version of libarchive...  stay tuned.

887bcd3995 Add statistics: track offset in compressed and uncompressed archive,
provide an interface for the client to query this information.

aee47dd7c8 More work on ACLs: fix error in archive_entry's ACL parsing code,
try to set ACLs even if fflag restore fails, first cut at reading
  Solaris tar ACLs

Code improvement: merge gnu tar read support into main tar reader;
  this eliminates a lot of duplicate code and generalizes the tar
  reader to handle formats with GNU-like extensions.

Style: Makefile cleanup, eliminate 'dmalloc' references, remove 'tartype'
  from archive_entry (this makes archive_entry more format-agnostic)

Thanks to: David Magda for providing Solaris tar test files

999103b3db Just use autoconf-compatible feature macros; don't try to be clever. 2004-03-22 05:17:23 +00:00

e5b478f765 Bug: Standard C still requires declarations to precede statements. <sigh>
Portability: Eliminate an accidental __unused, accomodate
  systems with non-POSIX strerror_r

df3c1316b0 Many fixes.
Portability: Thanks to Juergen Lock, libarchive now compiles cleanly
on Linux.  Along the way, I cleaned up a lot of error return codes and
reorganized some code to simplify conditional compilation of certain
sections.

Bug fixes:
  * pax format now actually stores filenames that are 101-154
    characters long.
  * pax format now allows newline characters in extended attributes
    (this fixes a long-standing bug in ACL handling)
  * mtime/atime are now restored for directories
  * directory list is now sorted prior to fix-up to permit
    correct restore of non-writable dir heirarchies

2710e4d1ef Initial import of libarchive.
What it is:
   A library for reading and writing various streaming archive
   formats, especially tar and cpio.  Being a library, it should
   be easy to incorporate into pkg_* tools, sysinstall, and any
   other place that needs to read or write such archives.

Features:
  * Full automatic detection of both compression and archive format.
  * Extensible internal architecture to make it easy to add new formats.
  * Support for "pax interchange format," a new POSIX-standard tar format
    that eliminates essentially all of the restrictions of historic formats.
  * BSD license

Thanks to: jkh for pushing me to start this work, gordon for
  encouraging me to commit it, bde for answering endless style
  questions, and many others for feedback and encouragement.

Status: Pretty good overall, though there are still a few rough edges and
  the library could always use more testing.  Feedback eagerly solicited.
